The question would be why you'd want those things - what you could achieve with them that you couldn't without!
In terms of more detailed stats, I was thinking of doing a kind of World of Darkness-style stat grid composed of Social-Mental-Physical on one axis and Power-Finesse-Resistance on the other, distribute +1, =0 and -1 between them and then add the results together in the grid (For instance, +1 Social, -1 Resistance means you're bad at keeping your cool; +1 Social, +1 Finesse means you're great at manipulating people, and you're quite [+1 Social, =0 Power] charismatic.) In terms of making each stat more mechanically significant (eg. "What can you lift?") I haven't seen anything like that and I can't really think of a reason to do it except in the broadest strokes - I think you're better off considering obstacles in terms of their narrative weight, and the moves already build a lot of detail into stats in the first place.
